What's the question you need help with today? (:

TheSmartOne (thesmartone):
we have inequalities graphed with a full line, not a dashed line
TheSmartOne (thesmartone):
If the inequality is < or > , the graph is a dotted line. If the inequality is ≤ or ≥ , the graph is a solid line.
So remove all the answer choices that have < or >
which answer choices remain?
OpenStudy (kingogcobraxx):
b and d

those are the answer choices that remain, now plug in (0, 0) and see for which equations (0, 0) is true :)

" plug in (0, 0) and see for which equations (0, 0) is true :)"
Pick one of the remaining answer choices. Plug in 0 for x and 0 for y, into the two inequalities. Show what you get.

0 ≤3x-1:x+30≥ 6
OpenStudy (agent0smith):
Looks like you plugged in 0 for y, but not for x
OpenStudy (agent0smith):
And how did you get 30? 3y means 3 times y. So if you plug in 0, it's 3*0, not 30
